Title: Peripheral section opening type coring gate for injection moldign
Inventor: TOMASU JIEE ROOZU
IPC: B29C45/28
Filed: 1985-04-12
Abstract: This invention relates to an improved core ring gated injection molding system. The valve pin has a tip portion which joins a larger diameter stem portion at a tapered shoulder and extends through the cavity into the mold platen on the other side. The tip portion of the valve pin is substantially smaller in diameter than the gate through the cavity plate, thus providing for the flow of melt through the gate around it when the valve pin is in the retracted open position. In the forward closed position, the tapered shoulder seats in the gate to provide a seal. By providing for operation in reverse directions to previous core ring gated systems, this increases cooling to the mold platen in the closed position and decreases it in the open position.

Filed: 1980-06-09
Abstract: PURPOSE: To improve the durability and efficiency of equipment by changing a supply time for lubricant responding to rotary speeds and by constantly and properly maintaining a pressing force to the inner wall of a vane' cylinder and by reducing wear of the inner wall of the cylinder.  
     CONSTITUTION: The higher a rotary speed is, the shorter the continuity time of a transistor 31 is. Therefore, the excitation time of a magnetic coil 39 is reduced. With this construction, the amount of lubricant supplied required for pressing a vane 46 to the inside wall of a cylinder 41 is reduced responding to an increase in the rotary speed of a vane rotary type compressor, while the pressing force to the vane 46 is also reduced. The pressing force of this lubricant as well as a centrifugal force effectively act on the vane 46. The centrifugal force is increased responding to an increase in the rotary speed of the vane rotary type compressor. This construction maintains a constant and proper pressing force to the inside wall of the cylinder 41 of the vane 46 and reduces abnormal wear of the vane 46 and the cylinder 41 and improves the durability and efficiency of equipment.
